Genus CYANIRIODES. 



Cijaniriodes, de Niceville, Butt of India, iii. p. 33 (1890). 



Two sub-costal nervules in the forewing ; vein 11 just after its origin touches 12, 

 but does not anastomose, there are no tails, there are however secondary sexual 

 characters ; the hiudwing of the male having an oval shining patch below and 

 adjoining the sub-costal nervure just before the middle, on which lies a short tuft of 

 hairs, which appears to be attached to the membrane of the wing close to the sub- 

 costal nervure ; there is also a small tuft of hairs placed close to the base, which are 

 directed upwards, and are partially covered by the forewing.

Imago. — Male. Upperside dark shining emerald-green. Forewing, costal margin 

 rather narrowly, outer margin broadly, black ; a black quadrate spot at the end of the 

 cell confluent with the black costal margin. Hiudwing, apex narrowly, outer margin 

 and anal fold broadly black. (H. H. Druce.) 



Female. Upperside, both wings pale violet-brown. Cilia alternated with 

 white. Forewing with a broad longitudinal medial lilacine-grey band, of a some- 

 what triangular form, disposed below the cell, the exterior border of the band 

 being scalloped. llindioing with a narrow medial discal similar-coloured band. 

 Underside, both wings purplish lilacine-white, with a blackish zigzag cell-streak, a 

 transverse zigzag duplex line, and two narrow similar sub-marginal lines, a slender 

 marginal line, and a waved anteciliary line. (Moore.) 



Expanse of wings, ^ ? 1^-^ to l-^-^ inches. 



Habitat. — Mergui, Borneo. 



We have seen only Hewitson's type ; Moore's type is in the Indian Museum, 

 Calcutta ; the figures here given are copies of Druce's and Moore's figures, de Niceville 

 says andersoni only difters from Hewitson's type in the pale blue band on the upper 

 side of the hindwing, which is larger in libna than in andersoni. Hewitson's type in 

 the B. M. is in poor condition, and has lost its abdomen ; the male (also a unique 

 example) is in coll. Cator. The females of all this group vary somewhat ; undoubtedly
